WEATHER-STRIP,

SPECIFICATION forming part of Letters Patent No. 650,637, dated May 29, 1900.

Application filed February 2, 1900. Serial No. 3,669. (No model.)

'To all whom it may concern:

provement in Weather-Strips; and I declare the following to be a full, clear, and exact de-' scription of the invention, such as will enable others skilled in the art to which it pertainsv to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to Weather-strips for windows, and has for its object an improved strip of metal adapted to be secured to the framework of a window and to engage with the sashes of the window in a way to prevent the rattling of the sashes in their seats or the passage of air around the sashes. At the same time the sashes are left free to be raised or lowered and can be made in the first in stance to so fit in their seats that the swelling of the sash-timber incident to damp weather will not cause the sash to bind in its seat.

In the drawings, Figure 1 is a horizontal cross-section of a side bar of the upper and a side bar of the lower sash of a window and of the frame in which the sash is 'seated.-

Fig. 2 is a cross-section of the upper crossrail of the lower sash and the lower cross-rail of the upper sash. Fig. 3 is a perspective of an end of the weather-strip used with the outside sash. Fig. 4 is a perspective of an end of the weather-strip used with the inside sash. Fig. 5 is a perspective of an end of the weatherstrip used on the meeting-rails of the sashes.

In Fig. 1, A indicates the side frame of the window. B indicates the parting-strip that extends upright between the two tracks or grooves that the sashes run in. 0 indicates the sash-stop at the inside of the frame. D indicates the blind-stop. a indicates a side rail of the lower sash, and b indicates a side rail of the upper sash.

The blind-stop extends inward from the frame-piece A. The parting-strip B is set in a groove in the frame-piece A and projects from the frame-piece extending into the open ing of the frame. The sash-stop O is set on the frame A, and there is thus formed between the blind-stop D and the parting-strip B a vertical groove extending from top to the bottom of the frame, and this groove constitutes the way or track that the upper sash travels in, and there is alsoformed between the parting-strip B and the sash-stop O a similar vertical groove which constitutes the way or track for the lower sash. Each side strip of the sash is provided with a shallow vertical groove that is cut into the side strip groove registers with the face of the strip next adjacent to it on the outside. Thus the side rail 1) is provided with a groove 0, that registors with the face of the blind-stop D.

The weather-strip e is made of sheet metal, one edge of which is provided with a flange 6, extending its entire length, arranged to engage in a groove d, that is cut vertically in the blind-stop. The opposite edge of the weather-strip e is turned back on itself, form ing a smooth edge e and also stiffening this part of the strip. Between the edge flange e and the returned or doubled-back edge e the web of the strip is bent with a single corrugation, forming a grooved part a which furnishes a track or rail fora screen f. The flange 6 both stiifens the strip and furnishes an edge engagement in the groove d that is perfectly tight against the passage of air-drafts. The edge e engages in the groove 0 of the sash and effectually prevents the sash from rattling and also prevents the passage of air-currents around the sash.

The weather-strip for the lower sash is like grooved part or corrugated part is omitted, and the web between the flange f and the recurved edge f is straight and flat. The recurved edge f engages in agroove 9 out vertically in the side rail aof the sash, and the flange f engages in a vertical groove in the parting-strip B. Both weather-strips are secured in the woodwork by nails.

On the lower side of the meeting rail of the outer sash is secured a weather-strip it, provided with a flange h, that is set into a groove k in the meeting-rail K. This weather-strip his arranged to project inward beyond the edge of the meeting-rail K, and the projecting part is grooved or corrugated with a corrugation If, that stiffens this part of the at a distance from the edge such that the the weather-strip e, except that the vertical weather-stri p and engages closely against the lower side of the meeting-rail of the lower sash.

What I claim is- 1. The combination of the blind-stop D, having a groove d, therein, a windowframe provided with a groove 0, a Weather-strip 6, provided with a flange c, said flange being adapted to lie fiat upon said blind-stop and being bent at right angles to extendinto the groove (Z, said weather-strip being bent upward and then downward to form a grooved part e and extending in a flange 6 along the surface of said blind-stop and into the groove in the window-frame, and a screen f, adapted to slide upon the grooved part, e

of the weather-strip, substantially as described.

2. The combination of a blind-stop D, a window-frame provided with a groove 0, a weather-strip 6, provided with a flange 6, said flange being adapted to lie flat upon said blind-stop, said weather-strip beingbent upward and then downward to form a grooved part a and extending in a flange 6*, along the surface of the blind-stop, and into the groove in the Window-frame, and a screen f, adapted to slide upon the grooved part 6 of the weather-strip, substantially as de- ,scribed.

3. The combination of a window-stop provided with a groove, extending longitudi nally thereof, a window-sash provided with a longitudinal groove 9, the inner bounding surface of which is approximately on a line with the outer surface of said stop, and a weather-strip provided at one edge with a flange f, of greater height than the depth of the groove in the window-stop, said weather-' ROBERT J.
